GRAZR Components Launch the Zone Pro, a High-End Singlespeed Tensioner
During our testing, we found that hex counter sunk screws rounded easily, as the socket for the hex tool is particularly shallow. We switched to the Torx socket head for reduced rounding and improved the durability for the user.

@megatryn: Our tensioner cages are made from 7075 aluminum, while the hardware and clutch adjustment dial is made from 304 stainless steel to prevent rounding.

Good question! The cog is case hardened, meaning it’s heated to an optimal temperature and dropped into a small vat of carbon. This only hardens the outer layer of the cog, while retaining the innate strength of the chromoly below the surface. Unlike a cassette, this cog takes the entire load of the drivetrain at all times, which is why the hardening process is necessary for extended durability.
The base of the cog is 5.5mm thick, which is significantly wider than individual cassette cogs, and wider than other singlespeed cog offerings on the market. This increased thickness helps spread the load from the cog onto the freehub body, reducing pressure on the freehub and therefore unnecessary wear. No freehubs are getting eaten here!
